And it's not the voltage that presents the real danger with electricity but the Amperage. I could touch something with a 50,000 voltage but if there isn't any amperage I won't be harmed but only half an amp is enough amperage to kill someone. That's the reason for the Danger High Voltage signs. It's because of the current which is measured in Amps. We use AC (Alternating Current) rather than DC (Direct Current) because AC can be pushed farther through wires than DC can. With a DC power Plant you would need a power plant every few blocks rather than one or two per average town. Many devices however need DC to run properly so the current is stepped down when it comes into a building and converted to DC at the point it enters the machine via it's power supply. And electronic devices are sensitive to voltage and amps. Too much and you end up frying chips.
